To all whom it may concern Be it known that we, DAVID E. Hosr, EARNEST W. Bowen, and RioHnY H. GoRDo-N, citizens of the United States of America, residing at Bowerstown, in the county of Harrison and State of Ohio, have invented certain new and useful Improvements in Automatic Stops and Trips for Cars, of which the following is a specification, reference being bad therein to the accompanying drawing. Y I

This invention relates to an automatic stop and trip for cars, and the prlmary object of our invention is the provision of simple and effective means, in a manner as hereinafter set forth, whereby an empty car can be automatically removed from an elevator or cage and a loaded car placed thereon, without any danger of either of the cars accidentally shifting during the movement of the elevator or cage or while-the elevator or cage is at a landing.

Another object of this invention is to pro vide an automatic stop and trip for cars that can be advantageously used in connectionwith mines having elevator or cage shafts, and various entries, landings or rooms in communication with the shaft.

A further object of our invention is to provide an automatic stop and trip that can be used in connection with the weighing scales of railways, where a car is temporarily held upon a scale until it is weighed.

A still further object of this invention is to provide an automatic stop and trip that obviates the necessity of labor and an elevator landing for unloading and loading cars.

A still further object of this invention is to provide an apparatus of the above type that consists of comparatively few parts that are easy to assemble, durable, inexpensive to manufacture and highly efficient for the purposes for which they are intended.

-With the above and other objects in view the invention resides in-the novel construction, combination and arrangement of parts to be hereinafter specifically described and then claimed.

Reference will now be had to the drawings, wherein Figure 1 is a plan of the preferred form of apparatus, Fig. 2 is a side elevation of the same partlybroken away and partly in section, Fig. 3 is asimilar view of a modified form of apparatus, Fig. 4 is an end view of a portion of the same, Fig. 5 is a perspective View of a portion ofthe same, Fig. 6 is a plan of a further modification of the invention, Fig. 7 is a perspective view of a portion of the same, Fig. 8 is a still further modification of the invention, illustrating chuck blocks, and Fig. 9 is a perspective view of a portion of the'same.

In describing our invention by aid of the drawings above referred to we desire to point out that we intend said views as merely illustrative of an example whereby our invention may be applied in practice, and we do not limit our claims to the precise arrangement and construction of parts indicated. The following description is therefore to be construed broadly as including substitute arrangements and constructions which are the obvious equivalent of those shown.

In the drawings, 1 denotes an elevator or cageshaft and movable in said shaft by the ordinary and well known type of hoisting mechanism is an elevator or cage Qprovided with a track 3 that is preferably supported by ties 4 located upon the elevator. The ties 4: support a plate 5 and located uponsaid plate are longitudinally alining bearings 6 for a rock shaft 7. The rear end ofthe rock shaft 7 has a crank S and connected to said crank is a coiled retractile spring 9 which is also connected to the outer end of a stop 10.

The inner end of said stop being normally engaged by the crank 8 to limit the movement of the rock shaft 7 and the action of the spring 9.

The rock shaft 7 has a slight longitudinal movement vin the bearings 6 in order that said shaft can yield without any danger of the same being injured and to hold said shaft in a normal position, a coiled compression spring 11 encircles the forward end of said shaft, between one of the bearings 6 and a head 12 mounted upon the end of said shaft. The head 12 has a crank 13 that is supported normally above a cam 14: carried by the plate 5. The rock shaft 7, adjacent to the rear end thereof, has a crank 15 provided with a stop 16; and the plate 5, adjacent to said crank, has a bearing 17 for a gravity latch 18. This latch cooperates with the stop 16 in locking a car 19 upon the elevator, the stop 16 engaging the forward side of an axle or bolster 20 and the latch 18 extending upwardly behind the axle or bolster, as best shown in Fig. 2.

The reference numeral 21 denotes an inclined track at one side of the shaft 1 and the reference numeral 22 a similar track at the opposite side of the shaft. The ties of the track 21 support a plate 23 that is bifurcated, as at 24. Pivotally mounted in the bifurcation of said plate isarelease lever 25 having the lower end thereof provided with a weight 26. Pivotally connected to the lever 25, as at 27 is an arm 28, said arm extending through a guide 29, carried by the plate 23. The forward end of the arm 28 is beveled and is adapted to ride upon the cam 14, elevate the crank 13, rock the shaft 7, lower the stop 16, and allow the car 19 to pass off of the track 8 onto the track 22.

The arm is automatically shifted by a car 30 striking the release lever 25, said lever shifting the arm 28 forward to accomplish the operation above described. As the car 30 passes onto the elevator 2 the forward axle or bolster of said car elevates the gravity latch 18 until the forward axle or bolster is engaged by the stop 16, which has been restored to its normal position by the coiled retractile spring 9.

In Figs. 3 to 5 inclusive there is illustrated a modification wherein the rock shaft 7 has the head 12 thereof provided with an elongated crank 31 that extends downwardly at the ends of the elevator cage 2 and is adapted to engage an elongated slide arm 32 when the cage is lowered. The slide arm 32 is shiftably supported in hangers 33 carried by a phu'ality of ties of the track 21. The outer end of the slide arm 32 is pivotally connected to a spring controlled release lever 34:, the latter being pivoted at its lower end in a bracket 3% arranged upon a block 34 at the bottom of a well 3% arranged forwardly of the track sections 3. The controlling spring 34? of the lever 3-l normally maintains the free end of the arm 32 in the path of the crank 31 to hold the elements 16 and 18 clear of the car. The spring 34 has one end attached to the lever 34- and its other end to a brac ret 34L. It will be assumed that a car traveling down the tracks 21 will push a car from off the tracks 3 onto the tracks 22, as the car traveling upon the tracks 22 engages the lever 34;, it will shift the same upon its pivot, carrying the slide arm 30 therewith, allowing of the rock shaft 7 to be actuated by its spring and move the elements 16 and 18 to engage the car traveling from the tracks 21 onto the tracks 3.

In Figs. 5 and 6 of the drawings a further modification of the invention is illustrated wherein the rock shaft 7 is prolonged and the forward end thereof provided with a head 35 having a cam 86. This cam is engaged by the axle or bolster of a car and the shaft 7 rocked to release a car that is held above the plate 5. It is this type of apparatus that can be advantageously used upon a track of slight inclination located in proximity to a scale where cars are Weighed.

A. still further modification of the invention is illustrated in Figs. 8 and 9, especially designed for an elevator or cage. The rock shaft 7 has a crank 37 connected by rods 38 to fulcrumed arms 89 located at the outer sides of the rails forming the track 3. The arms 39 have chuck blocks 40 adapted to extend over the rails of the track 3 and chuck the wheels of a car upon the elevator. In order that the chuck blocks 40 can be moved in unison over the rails of the track 3 it is necessary to use a pivoted arm 41 in connection with one of the fulcrumed arms 39. Coiled retractile springs 42 encircle the rods 38 for holding the chuck blocks normally over the rails of the track 3.

From the foregoing it will be observed that the automatic stop and trip can be used for controlling the movement of loaded and unloaded cars and while primarily designed for use in mines the principle of our invention can be embodied in an apparatus for industrial and other railways.

What we claim is 1. In an automatic stop and trip for cars, the combination with an elevator adapted to support a car, of a rock shaft supported by said elevator, a stop carried by said shaft, a gravity latch supported by said elevator and cooperating with said stop in retaining a car upon said elevator, and means operable by a car in proximity to said elevator for rocking said shaft to release the car upon said elevator.

2. In an automatic stop and trip for cars, the combination with an elevator and a car adapted to move thereon, of a rock shaft supported by said elevator, a stop carried thereby for limiting the movement of a car upon said elevator, a gravity latch supported by said elevator and adapted to cooperate with said stop for locking the car upon said elevator, and means in proximity to said elevator and including a car actuated cam for shifting the stop of said shaft to release the car upon said elevator.

3. In an automatic stop and trip for cars, the combination with an elevator adapted to support a car, of a rock shaft carried by said elevator, a stop supported by said shaft, a gravity latch carried by said elevator and cooperating With said stop in retaining a car upon said elevator, a release lever adjacent to said elevator and adapted to be DAVID E.
